Title: On-board principal automatic train control system
Inventor: WAJIMA TAKENORI
IPC: B60L15/40
Filed: 2001-07-27
Abstract: PROBLEM TO BE SOLVED: To improve the operating efficiency of a train. SOLUTION: A ground equipment 6 transmits the information on the block wherein a train stops and own block to an ATC control part 4 via other blocks, ATC receiving coil and ATC receiver. The ATC receiver reads the position of own train from a transponder wayside coil 7 via a transponder pickup coil 8 and recognizes it by updating all the time the positional information stored in a positional register by means of a speed pulse; in case no information is stored, the end of own block transmitted from the ground equipment is determined as the position of own train. Speed patterns preset at every train and every block are held in a memory 45 as database.  The ATC control part 4 reads the speed pattern corresponding to a stop block number received from the ground equipment 6 and outputs a brake command complying with a difference between the permissible speed and the speed of own train which are determined by the recognized own train position; however, in the block specified beforehand, a slower speed from between the speed determined by the speed pattern and a preset fixed speed is taken to be the permissible speed.
